public interface NonDelegatingURIResolver
This is a marker interface: if a URIResolver implements this interface and returns null from
its resolve() method, then the standard URI resolver will not be invoked.
The main use case for this is to support protocols that the standard Java java.net.URL class
does not recognize. In the case of doc-available(), we want to return false, rather than throwing
an exception in such cases.
